Before doing the treatment, a dental check is necessary to verify the absence of caries, periodontal pathology or any other oral condition. Otherwise, the effects may be harmful. Also, it is convenient to perform a dental cleaning.
The dental whitening technique most used in the dentist’s office is the mixed one: with a clinical and a mobile phase, although in some cases it can be one or the other.
The clinical session lasts about 30 minutes. After protecting the perioral soft tissues, the patient is given a peroxide gel in the mouth. “The concentration of the peroxide and the time of exposure must be personalized in each case, explains Dr. Serrano de Haro.
With a cold light lamp, the effect of the exposure is enhanced by shortening the time. “We have neglected -explains the dentist- the use of ultraviolet lights that were harmful to skin and mucosa and nowadays we work with modern lamps of cold light, LED type, that work at the optimal wavelengths for the release of molecules of oxygen.”
The second phase continues at home with the application of the whitening gel using splints for several hours a day over a few days, depending on the case.
“After the clinical session, a two- or three-tone reduction is achieved, something that is comforting for the patient who perceives whitening as one of the few premium dental treatments because it does not require anesthesia and hardly causes discomfort,” she says.
The most common and temporary side effect is dentin hypersensitivity, which can also be controlled with desensitizing products prescribed by the dentist. In cases of intense sensitivity, it is pertinent to make a prior treatment with these desensitizers.
